MANUFACTURE OF TYPE-BAR BLANKS.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed March 5, 1901,-Seria1 No 49,692. Renewed March 10, 1909. Serial No. 482,569.

To all whom it may concern:

Be it known that I, FRANCIS H. RIoHARDs, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful'lmprovements in the Manufacture of Type-Bar Blanks, of which the following is a specification.

This invention relates to the manufacture of typebar-blanks and has for an object to provide a construction for such a blank adapting the same for being fed through a machine or mechanism for the purpose of bringing different portions of the blank into proper relation to one or more type-making mstrumentalities during the course of providing the same with a series of types.

An embodiment of the present invention is represented in the drawing accompanying the present specification, and in this drawing Figure 1 is a perspective view of a typebarblank embodying my present invention. Fig. 2 is a longitudinal section on a somewhat enlarged scale of a portion of the typebarblank represented in Fig. 1. Fig. 3 is partly a plan view and partly a longitudinal section illustrative of a device for imparting motion to a typebar-blank constructed according to my present invention. Fig. 4 is a section on the plane of the line a;a: in Fig. 1, certain arts being broken away to show parts lying eyond. Fig. 5 is an end elevation of the blank and blank-feeding device as shown in gig. 3, looking toward the right-hand in that ure. Similar characters of reference designate corresponding parts in all the figures of the drawing. v

The ty ebar element herein represented as a typelbar-blank, designated in a general way by B, is adapted to move lengthwise through a slot 2 in a suitable holder. This holder is here represented in a conventional way only and as suggestive of the purposes fulfilled by the corresponding feature of the actual typebar-machine-viz., as a support and guide for a movable typebar or a blank element to be furnished with types in some suitable manner, and which in the present disclosure will be designated by a comprehensive term of typebar-blank. The holder,

designated generally by C, comprises in the present representation thereof a base-plate or block 3 provided with uprights 4 and 4 forming between them the before-mentioned slot 2. For the attainment of the lengthwise motion of the blank through the slot 2 I provide the blank with a series of shoulders adapted to coact with an appropriate actuator, designated generally by K, for moving the blank. The shoulders may be fixed relatively to the blank in any desired manner for instance, by forming them in the substance of the blank or upon a separate piece attached to the blank. When disposed upon the side face of the blank, however, their tops preferably will not extend beyond the plane of the face, the better to enable the blanks and typebars formed from such blanks to be closely assembled. I find it convenient to form these shoulders by providing the blank with a series of notches. Such notches may be located in one of the side faces of the blank and each notch is of a depth and length sufficient to provide an ample shoulder with which an actuator may contact.

I have shown one form of a suitable actuator, the same consisting of a spur-wheel 7c supported in the upright 5 to permit its teeth to engage with the notches '7 in the blank B. There is also shown a device in the figures of the drawing attached to the present specification for imparting intermittent forward movement to the blank by the motion of a reciprocating member 9, which comprises, as shown, a ratchet-wheel 1O rigid with the spur-wheel 7c. With this ratchetwheel 10 is adapted to engage a pawl 11 sup ported upon a vibratory pawl-arm 12 hinged to the reciprocating member 9. It is evident that from the reciprocation of the member 9 as here combined an intermittent forward motion will be imparted to the blank. It is contemplated that, ordinarily, the notches will be of such form as that each notch shall present oppositely facing shoulders; hence if the notches are of the proper width, the actuator will cooperate with the shoulders facing in one direction to move the blank forward, while the shoulders facing in the opposite direction operate to lock the blank against movement after adjustment. The oppositely facing shoulders of the notches 7 are shown disposed on planes transverse to the bar and of its path of feed movement, the faces of the teeth of the spur wheel 7c arealso disposed on planes transverse to said path of feed movement. This transverse disposition is efiective to maintain the accuracy of the advance of.

the bar along such path.

In using the term typebar-blank I Wish to include also a typebar and a bar or blank in any intermediate stage of its conversion from a blank to a finished typebar.

Having described my invention, I claim 1. A type-bar blank provided on one of its faces With oppositely facing teeth or shoulders, constructed to co-act With feed mechanism to successively feed the blank letterspace distances, the teeth or shoulders facing in one direction operating to move the blank forwardly and the teeth or shoulders facing in the opposite direction cooperating with the first-mentioned teeth or shoulders to lock the blank against movement after adjustment.

feed said blank letter-space distances.

3. A typebar blank having a series of regularly spaced-apart notches forming a series of shoulders facing in one direction and a series l of shoulders facing in the opposite direction and Whose tops extend to the plane of the face in which the notches are located, and the shoulders being constructed to co-act with feed mechanism.

4. A typebar blank having a series of rectangular sharply defined shoulders formed by notches extending from one side face partly through the blank and disposed on planes transverse to the line of feed of the bar and which shoulders are constructed. to coact with feed mechanism.

5. A typehar blank having a series of regularly spaced-apart notches forming series of shoulders facing in one direction and a series of shoulders facing in the opposite direction and disposed on planes transverse to the line of feed of the bar, and which series of shoulders are respectively constructed to coact With feed mechanism.
